NOTES:

BSR.7 = BLOCK STATUS

1 = Ready

0 = Busy

[1] RY/BY# output or BS bit must be checked to

determine completion of an operation (block lock,

erase suspend, any RY/BY# reconfiguration, Upload

Status Bits, block erase or data program) before the

appropriate Status bits (BOS, BLS) is checked for

success.

BSR.6 = BLOCK-LOCK STATUS

1 = Block Unlocked for Program/Erase

0 = Block Locked for Program/Erase

BSR.5 = BLOCK OPERATION STATUS

1 = Operation Unsuccessful

0 = Operation Successful or Currently

Running

The BOAS bit will not be set until BSR.7 = 1.

BSR.4 = BLOCK OPERATION ABORT STATUS

1 = Operation Aborted

0 = Operation Not Aborted

MATRIX 5/4

0 0 = Operation Successful or

Currently Running

0 1 = Not a Valid Combination

1 0 = Operation Unsuccessful

1 1 = Operation Aborted

Operation halted via Abort command.

BSR.3 = QUEUE STATUS

1 = Queue Full

0 = Queue Available

BSR.2 = VPP STATUS

1 = VPP Low Detect, Operation Abort

0 = VPP OK

BSR.1–0 = RESERVED FOR FUTURE ENHANCEMENTS

These bits are reserved for future use; mask them out when polling the BSRs.

NOTE:

1. When multiple operations are queued, checking BSR.7 only provides indication of completion for that particular block.

GSR.7 provides indication when all queued operations are completed.
